a slight trendp = 0.17
Although it was not considered a study outcome a priori, we also identified a slight trend (i.e., not statistically significant) toward higher preoperative seropositivity of anti-Col-V (78.6% vs. 56.5%, p = 0.17), anti-Kα1T (50% vs. 43.5%, p = 0.69), or either SAb (78.6% vs. 65.2%, p = 0.39) among patients with a manometric diagnosis of IEM.
